Data Encoding and Transmission with DIGIC NET Processing
The VB-C500D has a variety of control features.
Powerful DIGIC NET Processor The VB-C500D performs all image processing and encoding with a powerful, proprietary hardware-based compression and engine called DIGIC NET. Cameras that process or encode images via PC software use a lot of CPU power, which results in lowered frame rate. With DIGIC NET, each step of the image capture, processing, encoding, and transmission process uses virtually zero PC CPU power.
Simultaneous Data Distribution The VB-C500D can simultaneously deliver both M-JPEG and MPEG-41 video in high quality VGA size (640 x 480) at the maximum frame rate of 30fps- with no loss in frame rate, unlike many competing models. The high image quality of M-JPEG video is suited for live monitoring, while for recording MPEG-4 is ideal for recording due to its smaller file size and lighter network load. Furthermore, the camera supports IPsec and performs onboard data encryption without any loss in frame rate. Each camera offers support for up to 30 simultaneous clients (users accessing and viewing video images at the same time).
Multi-Streaming The VB-C500D can distribute M-JPEG images in three sizes simultaneously (640x480, 320x240, 160x120). The 160x120 size comes in handy for image upload mobile devices, the 320x240 size is useful when monitoring multiple cameras on a single screen, and 640x480 is ideal for saving when high image quality is desired.
Recorded Stream Functionality In addition to basic live video streaming, the VB-C500D is able to stream recorded video. This feature is useful when recorded images are viewed after the fact (rather than live) and greatly minimizes the chance of dropped frames due to data transmission interruptions.
If there is a break in data transmission, live frames from that period are typically not sent resulting in lost frames until the connection resumes. The VB-C500D's Recorded Stream Functionality enables the camera to retain and send the frames from that period to the recording server when the connection resumes. When playing back the recorded video, all frames are included, at the proper frame rate (up to 10fps).
